Application filed February 9, 1911. Serial No. 607,648.

To all whom it may concern Be it known that I, EDMOND TA'rnREK, asubject of the King of Hungary, residing at Budapest, in the Kingdom ofAustria-Hungary, have invented certain new and useful Improvements inAutomatic Cartridge-Magazines for Firearms, of which the following is aspecification.

M The purpose of the invention is, to improve the construction of themagazine-so that its getting out of order through the influence of thehumidity, the dust and dirt to which the magazine and its mechanism isexposed, is absolutely prevented. The im-- proved magazine furtherpermits of a uniform feeding of the cartridges to the gun withoutspecial mechanical devices so that the construction in general isgreatly simplified, the weight of the magazine being considerablyreduced. The improved magazine further can serve as a rest for the firearms whereby the aiming is greatly facilitated.

In the accompanying drawings the invention is shown by way of example.

F igure 1 is a longitudinal section through the butt end of a Browningrevolver with the improved magazine; Fig. 2 shows in vertical crosssection the magazine without its cover; Fig. 3 shows, on a larger scale,the spring actuated pressure device for the cartridges. Fig. 4 is alongitudinal section on an enlarged scale of the parts in Fig. 3.

According to this invention the magazine 2 is enlarged by a drum shapedextension 4. This drum shaped extension 4. is a continuation of themagazine proper 2 wound in spirals. This outer drum shaped extension 4of the magazine 2 can be used as a rest for the aiming drill. In themiddle of the drum 4 an axle 6 is revolubly mounted which is acted uponby a spring 5. The axle 6 carries on one end under the cover 7 of themagazine a guide piece 8 in which a sleeve 9 is guided. In this sleeve 9a rod 10 is telescopically mounted which carries at its upper end aroller 12 for pushing the cartridges into the gun. When the cartridgesare being placed in the magazine the movable sleeve 13 and with it therod 10 connected therewith are gradually depressed whereby, through theintermediary of the guide piece 9 the axle 6 is rotated and the springwhich acts upon said axle is automatically wound up. At the end of therod 10 mounted in the movable sleeve 9 an indicator 11 is fixed which isguided in a curved slot 17 of the cover 7 of the magazine and indicatesthe number of cartridges contained in the magazine. When the the arm isbeing used the cartridge which has just been fired is immediatelyreplaced by the next following cartridge which is automatically fed intothe barrel through the pressure of the roller 12. This pressure istransmitted to the roller from the spring influenced axle 6 by means ofthe sleeve 9 and pusher rod 10f I claim An improved automatic cartridgemagazine for self-loading fire-arms, comprising in combination acartridge tube, straight at the upper end, which is connected with thebreech of the gun and wound in spirals at the lower end, a cover forsaid lower end of the cartridge tube having a curved guide slot, atspring-influenced axle revolubly mounted at the center of the lower partof the cartridge tube, a guide piece fixed at one end of said axle, asleeve in said guide piece, a pusher rod telescopically mounted in saidsleeve, a roller in the upper end of said pusher rod bearing against thelast cartridge of the magazine, an indicator fixed at the outer end ofsaid pusher rod engaging with said guide slot of the cover,substantially as described and shown and for the.

purpose set forth.

In Witness whereof I have hereunto set myhand in the presence of twowitnesses. EDMOND TATAREK. Witnesses:
